State-of-the-art multidetector computed tomographic (CT) technology has replaced invasive angiography for evaluation of patients suspected to have aortic disease. Although most disease is associated with atherosclerosis (ie, aneurysms and dissection), the spectrum vast includes various congenital acquired entities. Radiologists should also be familiar uncommon diseases, which are divided into those that in origin disorders, their findings at CT. The first group patent ductus arteriosus,...
Determination of antinuclear antibodies (ANA) by indirect immunofluorescence (IIF) is usually the initial test for diagnosis systemic rheumatic diseases (SRD). Assigning predictive values to positive and negative results vital because lack knowledge about ANAs their usefulness in classification criteria SRD leads inappropriate use.Retrospective study, ANA tests requested different specialties, correlation patients' final diagnosis.The prevalence autoimmune disease was relatively low our...
A serological and bacteriological study was performed with sera taken from 2,228 swine six states in Venezuela. None of the animals were vaccinated against brucellosis, prevalence disease varied 5 to 89% on farms located these states. Our studies indicated that could be categorized into four groups depending degree reactivity tests. Brucella suis biovar 1 isolated lymph nodes, spleens, semen samples seropositive identified by oxidative metabolic techniques. B. not tissues seronegative even...
Background Aortic coarctation (AC) represents 7% of congenital heart disease. It is a reversible secondary cause systemic hypertension, however up to 35% patients remain hypertensive and 18% have cardiovascular complications such as aortic aneurysm, dissection or valve AC associated with bicuspid (BAV) in around 60%, both diseases alter wall distensibility, stiffness shear stress (WSS). Our objective was compare these parameters according the morphology (either tricuspid).
About 90% of cases acute pericarditis have an idiopathic or viral etiology. In some cases, it is possible to identify high-risk patients for whom hospital admission and specific etiology research are mandatory adequate treatment. Bacterial uncommon responsible less than 1% cases. Only 10 due Campylobacter fetus been documented worldwide. This case highlights the importance good cardiac imaging, with right clinical microbiology-integrated approach in pericardial disease.
Background Chagas disease is a parasitosis caused by the protozoan Trypanosoma cruzi. It endemic in Latin America, nevertheless it has spread to other regions of world due migration. Up 30% infected patients progress chronic phase, with 5-year mortality 50% heart failure or ventricular arrhythmias. We aimed compare function and delayed enhancement (DE) according predominant clinical presentation Chronic (CCD) either tachycardia (VT) (HF), as well CCD undetermined subclinical phases.
Photo: Yukun ChenThe balance of power in Latin America is shifting. Large, recently thriving countries like Brazil are struggling, hampered by domestic scandals. The economies oil-dependent Venezuela and Ecuador stagnant, while other nations, such as Chile Mexico, seem poised for growth. Amid this turbulence, striving to reposition themselves. World Policy Journal consulted a panel experts help understand what issues defining countries’ changing roles the region.The most pressing problem...
Introduction: Friedreich ataxia is an autosomal recessive and mitochondrial disease. A rare progressive inherited neurodegenerative disorder. Mutations in the frataxin gene result impaired activity of iron-sulphur containing enzimes within mitochondria: complex I, II, III aconitase.The cerebellum particularly vulnerable to intoxication, especially cerebellar cortex Purkinje neurons. In humans, most common cause a toxic lesion circuitry alcohol related, but also main target environmental...
Despite successful recanalization of the infarct-related artery, perfusion ischemic myocardium is not or incompletely restored in up to 30% patients due microvascular obstruction (MO). The presence it has been found be a predictor adverse events. CMR allows accurate assessment function, transmural extent and total size infarction, MVO all segments left ventricle.
Methods Thirty four patients were enrolled: twenty two males, twelve females, age between 15 days and 80 years old (mean 38 old) with diagnosis of cardiac mass underwent echo CMR before biopsy or surgery. Echo gradient cine images in multiple views, T1 T2 weighted sequences, additional information derived from first pass perfusion imaging inversion recovery post gadolinium delayed allowed an accurate the majority cases.
Methods CMR studies of patients with EA conducted from June 2007 to 2011 were analized. Cine spin echo images in multiple views, and angiography evaluated assess chambers morphology diameters, wall thickness left ventricular function, also measured the atrialized right portion functional tricuspid valve position. And Inversion Recovery sequence for determination fibrosis.
Pulmonary embolism (PE) is a highly mortal disease, currently assessed by pulmonary CT angiography. True-FISP MRI has emerged as an innocuous alternative that does not hold many of the limitations x-ray imaging. However, very sensitive to turbulent blood flow, generating artifacts may resemble fake clots in vasculature. These misinterpretations reduce its overall diagnostic accuracy 94%, limiting wider use clinical environments. A new segmentation algorithm proposed confirm presence real MR...
